When my girlfriend's friends come over for a visit they usually give the quick glance in the tank and they're done with it for the night. But when our roomate's boyfriend comes over he turns the light on and checks my guys and girl out for a few minutes then asks me some questions about them. It seems that the guys love the fish because they're big and unusual (for a non fish keeper) and the girls are pretty impartial, like cars or videogames pretty much. Girls like things that are cuddly, guys like fish that swallow other fish. Haha
